PACKING AND MULSI-IING IMPLEMENT.

Specification of Letters Patent.

Patented Aug. 29, 1916.

To all whom it may concern:

Be it known that I, LAURITS T. RAsMUs- SEN, a citizen of the UnitedStates, residing at Council Bluffs, in the county of Pottawattamie andState of Iowa, have invented certain new and useful Improvements inPacking and Mulshing Implements, of which the following is aspecification.

This invention relates to an improvement in packing and mulshingimplements, and has for its principal object to provide such a mountingfor the mulshing disks and packing wheels that, without increasing thedraft, they may be disposed at greater or lesser altitudes, whilerevolving, for engaging the surface conformation of the ground, so thatthe ridges and hollow places as well as the level parts of a field maybe reached by the wheels and disks.

The invention has reference to an implement provided with a flexibleshaft on which the packing wheels and disks are supported closely sideby side, said shaft being so mounted and supported that its parts mayswing freely and automatically to be disposed upwardly-divergent fromthe middle of the vehicle while moving in the valleys, channels orgrooves, and may swing readily and automatically to be disposeddownwardly-divergent from the middle of the vehicle while moving uponand longitudinally of the ridges.

The invention also includes means for permitting a limited longitudinalmovement of the flexible shaft, and means for a control for limitingsuch movement, and broadly consists of the novel construction,combination and arrangement of parts as described herein and claimed,and as illustrated in the drawing, wherein,'

Figures 1, 2 and 3 are rear views of the implement to illustrate therelative position of parts when moving in valleys as shown in Fig. 1, orupon ridges as shown in Fig. 2, or on level. ground as shown in Fig. 3.Fig. '-1 is a view of the implement in side elevation, the tongue beingbroken away. Fig. 5 is a view in longitudinal section through the tongueand frame. Fig. 6 is a partly broken end view showing normal positions,when in use, of the packing wheels and mulshing disks. Fig. 7 is a view,in side elevation, of one of the bearing-blocks for the flexible shaft.Flg. 8 1s a sectional view on line 8 8 of Fig. 7. Fig.

9 is a view in longitudinal section of a combined cylindrical bearingand ball mounting for connecting the inner ends of the flexible shaft.Fig. 10 is a section on line 10 10 of Fig. 6.

Referring to the drawing, numeral 11 indlcates an elongated frameconsisting of the parallel strips va and Z), preferably constructed ofangle iron, a pair of yokes or brackets 0 being provided and mountedupon the ends of said strips to project downwardly therefrom, each yokeor bracket being provided with a recess at opening on its lower end.

Numeral 12 indicates a tongue which is mounted upon the strips a and Z2,midway between the ends of the frame, and suitable inclined braces 13and cross pieces 1 1 are provided to sustain the stresses directed tothe frame and tongue, incident to the use of the implement, these beingdisposed and suitably secured upon the angle irons a and b.

Numerals 15 and 16 respectively indicate a pair of shafts having theirinner ends flexibly connected by means of a cylindrical boxing 17, bestshown in Fig. 9, each of their outer ends being mounted in a sleeve 18of a bearing-block 19 disposed in a recess (Z and pivoted loosely at eto the arms 7 which project downwardly from the brackets 0 of the frame,whereby, the shafts may have free, lateral or vertical and rotatablemovements with respect to each other while their inner ends areconnected, and may have limited movements longitudinally in theirhearings in the sleeves of blocks 19, subject to the king pins 20 whichtraverse the shafts at their ends while disposed in slots 8 of saidsleeves.

At 21 is indicated a link disposed below the tongue, its front end beingpivotally mounted at 22 in the bracket 23 which projects below and issupported by the tongue, its rear end providing a pivotal mounting orbearing for the inner end of shaft 16 adjacent to the ball 24 of saidshaft, this bearing beingsubstantially at equal distances from the endsof the frame.

The operation of the link is such that the shafts, at their inner ends,may have swinging movements in a limited arc, the center of which is thepivot 22. Since this pivot is disposed forwardly of and at aconsiderable distance, comparatively, from the shafts, said shafts willbe maintained subinner ends either upwardly ordownwardly through aconsiderable are.

Numerals and 26 respectively indicate packing wheels and .mulshingdisks, each of .the packing wheels preferably having a taperedperipheryg as shown in the drawing, a clrcular bearmg-surface h on the 1nner sideofits tire and a hub 7a extending at one of its endsoutwardly of theplane of its tire; Each mulshing disk is preferably provided withperipheral teeth as indicated at vm, and with a transverse rim or flangen of lesser diameter than the circular bearing surface it of a packingwheel. The wheels and disks thus described are disposed in alternationto circumscribe the shafts, the packing wheels having bearings thereonwith the ends of their hubs abutting upon each other. The mulshing disksare disposed with their transversely projecting rims or collars ndisposed in the vertical plane and in engagement with a part of thecircular bearing-surfaces h of the packing wheels. on account of thelesser diameters of the rims n of the mulshing disks as compared withthe diameters of the bearing surfaces 72, of the packing wheels, theirlongitudinal axes willnot at all times be 00- incident with the axes ofthe packing wheels,

and when the implement is moving forwardly they will be disposedsomewhat rearwardly of the packing wheels, with the result that theirteeth will simply perforate the ridges formed by the packing wheelswhich sustain the weight of the frame. It will be appreciated that wherethe wheels and disks are mounted on a single shaft having a considerablelength, the depressed areas of ground may not be reached by said wheelsand disks, and the ridges will be unduly compressed, but by use of theconstruction as described, these objectionable results may be avoided.

*Azs'best shown in Fig. 9, the cylindrical 7 box orsleeve 17 is providedat one of its terminals with a plate 39 which eircumscribes the shaftl6- to prevent a movement in one direction of the ball 24, a movement ofthe ball in an opposite direction being prevented by theconcavedterminal 1' of shaft 15, the

last named shaft being secured to the sleeve by pins 27. It isunderstood that the ends of theseshafts will project somewhat fartheroutwardly of the vehicleframe when disposed in alinement than whendisposed will slide in the slots 8, as mentioned. As shown in Fig. 1,the packing wheels which are mounted on the cylindrical box or sleeve 17(said packing wheels being generally one or two in number) are providedwith hubs h of such diameter that they will have a bearing upon saidbox.

Numeral 28 (Figs. 4 and 5.) indicates an aperture for receiving a boltwhich may traverse the aperture 29 of strip 30, for mounting adoubletree (not shown), this being comparatively near to the vehicleframe,

said strip 30 being below the tongue and sustained by the spacing-block31.

. Numerals 32 and 33 indicate apertures formed at longitudinal intervalsin link 21 forthe purpose of causing the inner ends of shafts l5 and 16to be disposed nearer to the V tongue than as above mentioned, whenpivotally connected with bracket 28, so that each of the shafts may havean outward and rearward inclinatlon from their lnner ends, the loosepivotal mounting a permittmg this inclination, the result in operationbeing be imposed in this respect since the scope of the invention isdetermined by the appended claims.

I claim:

1. An implement for the purpose described, comprising, in combinationwith a said shafts to permit them to move longitudinally in saidbrackets and to permit them to swing in a limited are, and means tolimit the longitudinal movements of the shafts in said brackets.

2. In an implement for the purpose described, a vehicle frame providedwith brackets at its ends, a pair of bearing-heads each being mountedpivotally in a bracket to permit swinging movements substantially atright angles to the line of draft, sleeves provided with slots andmounted in the bear;

a member engaging one of said shafts and connected w1th the vehicleframe for permitting coincident longitudinal and swinging movements ofthe shafts and for main taining the shafts during their movementssubstantially at right angles to the line of draft, and means disposedin the slots of the sleeves in engagement With the shafts for limitingthe longitudinal movements of said shafts in one direction.

3. An implement for the purpose described, comprising, in combinationWith a vehicle frame provided at each of its ends with a bracket, ashaft provided at one of its ends with a ball, a second shaft providedat one of its ends With a cylindrical housing, said shafts beingdisposed end to end with their outer ends flexibly mounted in saidbrackets, the ball at the end of the first named shaft being disposed inthe cylindrical housing of the second shaft, a Wheel journaled on saidcylindrical housing, Wheels journaled on each shaft, a link pivotallysupported by the frame and flexibly connected With one of said shaftsfor permitting the shafts to move longitudinally While swinging in alimited arc, and means on the shafts for limiting their longitudinalmovements.
